I would start with an RDA or RBA first to practice coil builds and making them work for what you've got utilizing wire gage and coil styles. It's half art form and half science/math. If you're not good with the science/math part at least you have protection with your regulated mod. Once you're ready you can step up to a mech. Do some research and watch some reviews too. It will help. Go to your local B&M and ask them to give you a lesson on mechanicals and coil builds. Most likely they will be happy to get you interested in new equipment (if they're good business minded people) so long as you spend money in their shop. Some good hands on time was the best way for me to decided when I was ready.
IMO if you're looking for your FIRST mod get something simple that doesn't require any tinkering to get it right. It has been said before in this thread, get a nemesis clone or a private v2 clone. Very simple operation and the clones have been back engineered and re-engineered over and over again (that's why you see so many of them)... AND they're relatively inexpensive. Spend the money on some good batteries. The batteries will be the difference from an epic vape or catastrophic accident.
Be patient and learn the art and science of mechanicals the right way. Save money with a simple clone. Spend the money on good batteries.
Good luck.
Yeah, I have been playing with my Kayfun Lite Plus revision 2 and my ERA (with the holes drilled out bigger) but I'm not really into the drippers. What other decent priced RBA Tanks would you suggest? I tried the Fogger v3 and I didn't like that so I sold it. I would love to get one of the Doc Dave Steam Turbines or a Vicious Ant Cyclone Top Feed AFC but man they are expensive! What's some other good tanks (22mm)?
